Find LCM of 861,720,873,723,268 with Prime Factorization


2 861, 720, 873, 723, 268
2 861, 360, 873, 723, 134
3 861, 180, 873, 723, 67
3 287, 60, 291, 241, 67
287, 20, 97, 241, 67

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 3 x 3 x 287 x 20 x 97 x 241 x 67 = 323651759760

Therefore, the lowest common multiple of 861,720,873,723,268 is 323651759760.

LCM Formula to Find Lowest Common Multiple of 861,720,873,723,268

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

861 x 720 x 873 x 723 x 268 = 104863170162240

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

861 : 1, 3, 7, 21, 41, 123, 287, 861

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

873 : 1, 3, 9, 97, 291, 873

723 : 1, 3, 241, 723

268 : 1, 2, 4, 67, 134, 268

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,720,873,723,268, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

720:2x 2x 2x 2x 3x 3x 5

873:3x 3x 97

723:3x 241

268:2x 2x 67

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 3x 3x 3x 3 = 324

Therefore, the value for common factors is 324.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 104863170162240/(1x324)

LCM = 104863170162240/324

LCM = 323651759760

Thus, we can understand that the LCM of 861,720,873,723,268 is 323651759760.
